IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 160,069, dated February23, 1875; application filed February 8, 1875.

To all whom it may concern:

Be it known that I, ALBERT ALBERTSON, of Jersey City, county of Hudson,State of New Jersey, have invented certain Improvements in Lamps, ofwhich the following is a specification:

The object of my invention is to provide for means of supplying theflame of a lamp with the required atmospheric air in order to obtainperfect combustion without using a chimney, or employing clock-work orother such motive power. My invention consists in placing through thecenter of a cylindrical wicktube a hollow tube or pipe, covered with ahollow cap at the top, and provided with a number of hollow arms at ornear the lower part. This tube or pipe, as well as the cap and arms, arefilled with mercury or any other desirable fluid, which, when heated bythe flame of the lamp coming in contact with the said hollow cap,communicates the heat downward through the fluid, which againcommunicates the heat to the metal, and, by radiation, heats theinterior of'the wick-tube. This wick-tube, being open at the bottom,permits the air to enter, which, being rarefied by the heat in the tube,ascends rapidly and supplies the flame with the required air. The oil issupplied to the wick-tube by aid of an oil-reservoir, as shown in Fig. Iof the drawings, or this reservoir may be placed at any desired distancefrom the lamp, and communicates with the wick-tube by aid of a pipe, asshown in Fig. IV.

I do not confine myself to any particular form, shape, or construction,as long as the lamp is so constructed that a space is left in the centerthroughout the whole lamp for the reception of the hollow tube with itsarms or branches, and for supplying the flame with the requiredatmospheric air.

In the drawings, Figure Irepresents a lamp with the oil-reservoirsurrounding and forming a part of the wick-tube, embodying my invention.Fig. II is a detached top view of the hollow cap and tube, with the armsor branches. Fig. III is a detached top view of the supports for thecap, tube, and arms. Fig. 1V represents a lamp with a separateoil-reservoir, connected to the wick-tube by a tube.

A is the foot of the lamp; B, the oil-reservoir; c, the 'inner, and dthe outer, wick-tube. F is the tube with hollow cap G at the top, andarms or branches I at the lower end and upward. h is the cylinder whichforms the space in the center of the lamp for supplying the air to theflame. J are the supports for the hollow tube F with cap and arms. K isthe oil-reservoir, which is connected by tube L to-the lamp M.

Having thus described my invention, I desire to claini The hollow tube Fwith hollow cap G and branches I, in combination .with a lamp withcylindrical wick-tube and cylinder h, substantially as described, andfor the purpose set forth.

ALBERT ALBERTSON.
